So I want to buy a jlpt level 4 mock test, because I don't want to go to washington just to take the easiest level, and you must know 800 words right? so what I do is take 10 words at a time and right them while saying them every day. Then take 4 at a time and write the actual word with kanji. IS this a good idea, or is there a better method to memorizing words.

I made little flashcards to carry around and study, but ... when I started studying for the JLPT I knew enough to pass at least level 3 with no problems, so I knew most of the words I was studying, and how to use them (is it a verb, noun, or adjective?)
